Methods for Treating Wastewater and Manure at a 500-Head Small-Scale Pig Farm in Rural Areas
AbstractA biogas digester can be built, and professional wastewater treatment equipment can be used to automatically separate the biogas residue and biogas slurry, so that the wastewater treated by the equipment can meet the safety discharge standards set by the state.
Nowadays many people want to set up a pig farm, hoping to increase their income through it. However, when setting up a pig farm, there are many issues to consider. Pig farms produce a fairly large amount of wastewater and manure, so what methods should we use to deal with them? In fact, there are many techniques for solving this.
Wastewater Treatment Methods for Small-Scale Rural Pig Farms
1. For small-scale rural pig farms, when treating wastewater, a biogas digester can be built, and specialized wastewater treatment equipment can be used to automatically separate the biogas residue and biogas slurry. Then the wastewater treated by the machine can meet the safety discharge standards set by the state.
2. When purchasing equipment, be sure to pay attention to the quality of the equipment. It must be a qualified and safe product that complies with national standards. Otherwise, poor wastewater treatment will allow it to produce some bacteria when it is reused to flush the pig farm, affecting the health of pigs and humans.
3. Then the water pipelines should be properly installed. The drinking water pipeline and the flushing pipeline should be separate; otherwise, cross-infection may occur. For the flushing pipeline, choose a toilet-flushing pipeline, as this is somewhat safer.
Manure Treatment Methods for a 500-Head Pig Farm
A 500-head pig farm actually produces quite a lot of manure, so when handling it, the treatment work must be done well.
1. A manure fermentation bed can be chosen for treatment. The manure fermentation beds available now are quite good. There are many types of manure fermentation beds, and the independent fermentation bed is quite good. Its raw material choices are also relatively broad, and after fermentation, the manure can be used as fertilizer for crops.
2. Black soldier flies can be bred. This insect has become a fairly common insect on farms in recent years. Its adults do not fly and will not affect the human environment and life, and its ability to treat manure is very strong. It can convert useless manure into higher-quality insect protein manure, which can be used as fertilizer.
3. There is also a simple method: pile the pig manure together yourself and let it ferment. You can sprinkle some lime on top, and after about one month, it can be used as fertilizer.
After reading the above about pig farm wastewater treatment and manure treatment, everyone has probably gained a better understanding of these aspects. For manure treatment, a fermentation bed can be used. For wastewater treatment, specialized wastewater treatment machines can be chosen to solve the problem.
